My friend yelled at me the other day for the exact same issue.
At least I can copy and paste this post now to show it wasn't me
Really annoying though, and this is my 2nd Pearl, now with O2 OS (formerly was on a peral w/ Rogers OS, had it exchanged but turned out to be a T-mo network issue in my home area that they finally fixed)
So on the 2nd pearl, 3 diff OS'es same problem... Really Frustrating
